- hIn the Campbell' application, Serial No.

ff- 383,190, iiled August 3,' 1929, Yfoi" sealing A20 mechanism for metal windows, is described a 'method'of maintaining the sash "plates u'n-y der tension so thatthey are drawn towards the balileor partingstrip, avoiding af'tendv encyl of the sash to rattle.

95 According to my present'invention, 'whichy relates to sealing mechanismlof the general typev and character described above, I pro-l vide a wide strip ot 'metal weather'stripping ,M- which completelycovers'tlie parting' strip q n *tween the baie 12 and chain pocket 26, and

' 30 orb'a'iile upon its inner wall, being anchored thereon, and which has*l projecting flanges which combine with proper lsealing strips upon the sash platesin orderv to give tension -f so that the sash' plates maybe drawntowards 35 the parting strip to avoid rattle. VThis construction also avoids complexity in assemblage as it permits the large strip simply to be slipped over the baiie onits inner'face and there positioned by thev same screws which anchor the baffle.l The advantages in simplici'ty of structure `and in assembly are inanifest to thosel skilledin the art.

- IIt is to be understoodthat the illustrative vexample set forth in the (accompanying draw'- ings can be easily-modifiedv to include the featureifof thefelt pocket upon the sash plate weather stripping as shown in'my copending Vapplication for absorbent weather stripping 1930, and that itmay also be modified to inthmamb and. very naar forwindOws,`Serial No. 453,920, filed May 20,V

clude the' same type of dissimilar metal sheathingplaced upon'the sash plate as il- Qlustrated insaid absorbent weather` stripping application.

. Furthermore, 1n metal windows, such-as aluminum, a. dissimilar metal weather stripping-jacket, formed :for instance of zinc, over v the bafileywill preventbinding between the baffle edge thesash plate. j

' AInrthl'e accompanying drawings, Fig. 1 represents ,a crossl section of appart` of va metal window incorporating-my invention, Fig. 2 isa fragmentary sidejelevationof the inner jamb wail,showinglthe weather stripping lja'claetefd overjthe battle, and Fig; 3 represents 65 a perspective lview of a weather` stripping jacket adapted to be placed y'over the bafie,V

withf the proper flanges lto enter the sashv plate openings.

In the gures, a wide metal weather vstri-pV 'm i designated vas 10.is jacketed overV the Yparting strip or baffle l2, in such manner that two projecting .tlanges`14land 16 enter the en'- larged chambers 18 and 20preferably'at anV angle ofpslightlylessthan 90, although this angle of entrance may be varied greatly in practice. Upper sash plater22, and lower sash plate 24 respectively enter the' enlarged openings 18and `20 Ythrough the spaces bey 'S0 cover 28. v Y s vv As illustratedV spring members k30 are hookedaround the edges ofthe respective sash plates and in such mannerY astdmove with the sash plates, and` have a forwardly vprojecting arm designatedjas 31 which is adaptedto maintain a spring` tension and Vsliding contact with the inner sides of Hanges 14 and 16 of the baffle jacket weather strip-l ping 10. lhus a portionof the flangesprojects between a partof the spring members 30 and the sash plates. Although notV shown in the drawings, it is manifest'that lspring me mbers 30, Vif desired, could be provided with the felt pockets as an 'additional guard against the entrance 'of wind'and rain, as shown in my application, Serial No. 453,920 aforesaid. y n l As indicated'by Figures 2 and 3, the baffle weather stripping jacket 10 is preferably /f notched at 32 to allow the positioning of rubbing block 34, although this notching is not strictly necessary, as the rubbing block could be mounted if desired over the baille weather stripping jacket.

It is apparent that the spring tension between flanges 14 and 16 and spring members 3() should, in order to gain the full advantages described, be light enough to gently draw the sash towards the baffle to prevent rattling, and yet not be of such force so that serious binding between the sealing members and jacket flanges will take place. Ordinarily speaking the baffle weather stripping jacket will be of such construction that its flange members-will not have a greatdeal of springiness, but it is obvious that this may be modiied at will to include some resiliency.

It will be seen that where the metals employed in the construction of the window tend. to bind, 'such as aluminum, that by interposing between plates 22 and 24 and the edges of baille l2, a jacket 10 of-a dissimilar metal, such as Zinc, that binding dueto similarity of metals, suchras formerly took place between the baille and sash plate will be eradicated. Y

As shown by Figures 2 and 3, the bae weather stripping jacket l0 is attached to the baille by means of screws or bolts through the holes 36, andthese same screwsor bolts,l if desired, may be the assemblage units for attaching the baffle to the partition strip in the customary manner. Y

From the foregoing description it will be seen that my invention consists, in this type of window, in the provision of a weather stripping jacket encompassing the inner wall of the baffle and projecting into the inner chambers in such fashion that where dissimilar metals are used that binding veffects arel avoided, and so that rattling is eradicated by slight tension placed upon the sash plates, drawing them towards the baille, and also in the provision of a. weather stripping unit extending substantially the entire length of the baille in preferably integral fashion, having flanges at either side of the baille to be used in conjunction with the usual spring members attached to thesash plates. The illustrative example set forth is an embodiment of my invention in a simple form but may be modified in many ways without departing from the spirit of my invention.

W'hat I claim is:

l. In a window of the type having jamb openings through the inner walls of the jambs, a baille forming part of the main jamb wall between such openings, sashes having members adapted to Vextend through such openings and resilient sealing members upon said sash members, a plate mounted upon the face of the baille provided with flanges 1- projecting into said openings between the sash members and the baiile edge and contacting with said resilient sealing members, said flanges extending between the sash members and the sealing members.

' 2. In a window of the type having jamb openings through the inner walls of the jambe, a baille forming part of the main jamb wall between such openings, sashes having members adapted to extend through such openings, resilient sealing members upon said sash members and a rubbing block mounted upon said baflle, an integral sheet of metallic weather stripping running upwardly and downwardly the face of said baille, said sheet having 'its edges bent to project into said openings and being notched in its center for said rubbingblock, said bent edges being adapted to contact with said sealing members` under tension and extend between-the sealing members and said sash.

members, whereby the sash plates are drawn towards the baille edges.

v 3.
